crypto/algif_skcipher.c in the Linux kernel before 4.4.2 does not verify that a setkey operation has been performed on an AF_ALG socket before an accept system call is processed, which allows local users to cause a denial of service (NULL pointer dereference and system crash) via a crafted application that does not supply a key, related to the lrw_crypt function in crypto/lrw.c.

Security readout for executives and security teams

CVE-2015-8970 is a Linux kernel flaw where a local user could crash an affected system through the kernel crypto socket interface. The business impact is availability loss, not disclosed data theft or remote takeover. The source bundle identifies the affected upstream range as Linux kernel before 4.4.2. Exposure is most relevant on Linux systems running vulnerable or unbackported kernels, especially where untrusted local users or workloads can execute code. The bundle does not provide a complete vendor/version matrix beyond upstream before 4.4.2 and referenced Red Hat advisories. Treat this as a controlled patch-management item unless vulnerable systems host untrusted local users or workloads. The main risk is service disruption from a local crash path, so priority rises for shared infrastructure and externally supplied workloads. Mitigation focus: Update to a kernel containing the upstream fix or a vendor backport.; Review the referenced Red Hat advisories for affected distribution packages.; Prioritize shared hosts, multi-user systems, and container platforms with local workload execution..
